1, Flat Face PDC Non-coring Bits (Newest Design) Description: This kind of diamond tool has good performance for various rock formations, and it is mainly used for general drilling. The powdered metal matrix ensures strong abrasion resistance and long service life. Advanced geometric design is adopted for fast penetration.2, PDC Face Discharged Coring BitsDescription: With the advantages of good cutting fast penetration, fluent water passing, high efficiency in getting core and long bit life, our PDC face discharged coring bits are applied soft to medium hard rock formation. 3, Multi-Blade PDC Non-coring BitsDescription: Multi-blade PDC non-coring bit is designed for opening holes. Standard PDC cutters are distributed on the blades. Balance design is used to improve the stability and efficiency of drilling. It has the advantages of fast penetration and high drill efficiency in soft rock. 4, Round Profile PDC Non-coring BitsDescription: This product only has small interface with the rock. Column diamond is used to protect inner and outer gauge, in addition, extra PDC cutters are used to enhance gauge protection. The bit can be cleaned and cooled sufficiently due to the design of flow roomage. This product is widely applied to soft to medium hard rock formation. 5, Three (Four) Wings Round Profile PDC BitsDescription: Our round profile PDC bits are improved according to oil bits. High performance PDC cutters adopted can highly decreases the cutting resistance and maintains a long service life. This type bits have faster penetration, longer life and stronger adaptability than conventional concave multi-wing bits. It is widely applied to medium soft rock formation. 6, 3 Blades PDC BitsDescription: This product is a new design type blade bit. It has three blades and capacious flume. 3 blades PDC bits enjoy the features of high drilling efficiency and fast penetration. The capacious flume ensures that water can pass through it quite fluently. They are applied to medium hard rock formation. 7, PDC Reamer BitsDescription: PDC Reamer bit is applied to reaming and drilling in medium hard rock. With the features of good guidance capability, sharpness, stable use and abrasion resistance, our PDC reamer bits are widely applied in medium hard rock.8, Three Wings Concave PDC Non-coring BitsDescription: The stability and efficiency of drilling are largely improved owing to the balance design of cutters. Flow roomage is specially designed so that bit can be clean and cooled sufficiently. This type PDC bit enjoys the features of good stability and universality. It is applied to soft to hard rock formation. 9, PDC oil coring set bitDescription: With the features of stability and high performance, this product is specially applied to oil drilling.10, Normal complete-pieces PDC BitsDescription: This product is widely applied to soft to hard rock formation. It adopts the wearproof material which maintains a long service life of drill. specifications:25mm 28mm,30mm,32mm,36mm,42mm.
